(B) Introduction of badminton competition methods and main rules
1. events: men's singles, women's singles, men's doubles, women's doubles, mixed doubles, men's teams and women's teams.
2. The scoring methods and rules of the new competition:
(1) Similar to the previous table tennis scoring method, the scoring system of 2 1 is adopted, that is, the scores of both sides reach 2 1 first, and two wins in three games. After each game is tied at 20, if one side leads by 2 points, the game will win; If the two sides are tied at 29, and one side leads 1 point, the game wins.
(2) In the new competition system, every ball is scored. Except for special circumstances (such as the floor is wet and the ball is broken), players can no longer ask to interrupt the game. However, when one side leads 1 1 in each game, 1 minute will be suspended to allow both sides to wipe their sweat and drink water.
(3) The scorer has the right to serve. If the scorer scores an odd number, serve from the left; Double the score and serve from the right. In the third or only one game, when the score of one side reaches 1 1 first, the two sides exchange venues.
(4) There are many changes in the rules of doubles, and the text is difficult to express, so it can't be mapped for the time being, so it is omitted here.
3. The scoring method of the old competition:
(1) Unless otherwise agreed, the best of three games will be adopted in the competition and the best of five games will be adopted in the team competition.
(2) Only the server can score.
(3) The player who scored 15 in doubles and men's singles won a game.
(4) The player in women's singles 1 1 wins one game.
① When doubles and men's singles are tied for 13 or 14 (women's singles are tied for 9 or 10), the player who gets 13 or 14 first (women's singles get 9 or 10) can choose "rematch". (2) This choice can only be made before the specified score appears for the first time and the next serve. ③ If the draw is 13 (women's singles 9), don't choose "rematch". If the draw is 14 (for women's singles, 10), those who score 14 (for women's singles, 10) can still choose "rematch".
(5) After selecting "rematch", scores will be reported from "0 to 0", and the player who gets the "rematch" score first wins.
① 13 draw lots, and the first team will give 5 points. (2)14, one side will get the third point if it is tied. 39. The draw will last until one team scores 3 points first. ④ 10 draw, and the first team scored 2 points.
(6) Starting from the next game, the winner of the previous game will serve first.
3. Position in the competition:
Single:
(1) When the server scores 0 or even, both players should serve or receive the service in their respective right service areas.
(2) When the server scores an odd number, both players should serve or receive the service in their respective left service areas.
(3) In case of "rematch", the server will determine the ranking according to the total score of the match. If the total score is 15 (odd number), both players should serve or receive from their respective left tees; If the total score is 16 (even number), both players should serve or receive the service from their respective right service courts.
(4) After serving, the players of both sides are no longer restricted by the service court, and can hit any position of the opponent's court freely, and players can also stand in or outside their own court.
Doubles:
(1) At the beginning of a match, both the winning side and the other side should serve from the correct service court.
(2) Only the receiver and the receiver can receive the service; If the opponent catches the ball or is hit by it, the server scores one point.
(1) The player who serves first at the beginning of each game must serve or receive the service in the correct service court when his team scores 0 or even; When the score is odd, you should serve or receive the service from the left tee.
(2) The player who receives the service first at the beginning of each game must receive or serve in the correct service area when his score is 0 or even; When the score is odd, you should receive or serve in the left service area.
(3) The above two completely opposite forms of standing are suitable for your partner.
(3) After the local server loses the right to serve in any match, the server will serve the player first, then serve the player's companion first, then serve by one of their opponents, and then serve by another opponent, thus transferring the right to serve.
(4) An athlete shall not make a mistake in serving, and shall not serve twice in the same game.
(5) The player who wins a game can serve first in the next game, and the player who loses can receive the service first.
(6) After serving, it is no longer restricted by the service area. Athletes can stand freely in their own field and hit the ball anywhere on the field.

The back serve line is the bottom line. The serve is valid between these two lines.
The front serve line of doubles is the same as that of singles.
The back serve line is the line before the baseline. The serve is valid between these two lines.
Badminton should have 16 feathers fixed on the ball support, and the length of the feathers is 64 mm to 70 mm, but the length of the feathers of each ball should be the same from the support surface to the tip of the feather. The top of the feather is round, the diameter is 58 mm to 68 mm, the diameter of the ball holder is 25 mm to 28 mm, and the bottom is round. The weight of badminton is 4.6 g to 5.50 g. For non-badminton, we need to make it into a skirt, and the quality and performance should not exceed 10\%. For the game ball, it must be tested before it can be used. The correct way is to stand on the end line, hit the ball forward and upward with the low hand, and the flying direction of the ball is parallel to the sideline. A qualified ball should fall between 53 and 99 cm from the opponent's end line.
[Edit this paragraph] Badminton common terms
First of all, badminton court
The badminton court is a rectangular court, with a length of13.40m, a doubles width of 6.10m, and a singles width of 5.18m. The center of the court is equally divided by the net (the height of the columns on both sides is1.55m, and the height of the net is1.525).
Badminton court is horizontally divided into two halves by the middle line; Vertically divided into frontcourt, midfield and backcourt. The front court is the court between the front serve line and the net; Backcourt refers to the court of doubles from the end line to the back serve line; The midfield is the field between the front serve line and the back serve line of doubles.
Second, stand and hit the ball.
The position where an athlete stands on the badminton court is called a standing position. There are two kinds of stations: one is a restricted station. For example, when serving and receiving the service, the athlete must stand in the prescribed area (left half or right half) as required; The other is an unrestricted position, which can be selected according to the needs of yourself or your partner (doubles). For example, the position of singles is generally near the center line from the front serve line 1 m, and the position of doubles can be selected according to the specific tactical needs of the two doubles players.
According to the above division of badminton courts, unrestricted stations can be divided into left half-court, right half-court, frontcourt, midfield and backcourt.
Hitting refers to the moment when an athlete swings to hit the ball. The player standing in the left half to greet the opponent's incoming ball is called left half stroke, the right half stroke is called right half stroke, and the frontcourt, midfield and backcourt strokes are called frontcourt stroke, midfield stroke and backcourt stroke respectively. In addition, according to the height of the incoming ball, we can divide it into overhand hitting (the incoming ball is above the shoulder and the hitting point is on the shoulder) and underhand hitting (the hitting point is below the shoulder).
Third, clap your hands.
Clapping your hands is to correct the hand holding the racket. A hand that does not hold the beat refers to a hand that does not hold the beat.
In badminton, we often hear terms such as forehand technique, backhand technique, forehand stroke and backhand stroke. The forehand technique refers to the technique of holding the racket on the same side; Backhand technique refers to the grip technique of different sides. For example, the technique used by right-handed players in playing right-handed ball is called forehand technique, from which technical names such as forehand serving technique and forehand hitting technique are derived.
In badminton, the function of non-grip racket is mainly to hold the ball and throw the ball when serving; Used to balance the body when hitting the ball, so as to hit the ball more effectively.
Fourth, the basic route of hitting the ball
The so-called hitting line refers to the trajectory relationship between the ball in the air and the field after the player hits the ball.
Badminton players cannot count the number of hitting lines. The following only studies a few basic lines that determine the rules of badminton lines.
We only analyze the route name of the ball by the player hitting the ball three times with forehand. The first line from one's right to the other's left (which is parallel to the sideline) can be called a straight line, the second line to the other's right (which has a large angle with the sideline) can be called a diagonal line, and the third line to the other's center line has a small angle with the sideline) can be called a middle road. Similarly, the three basic hitting lines of backhand backcourt (midfield and frontcourt) can also be called this. You can combine forehand and backhand when addressing. Such as forehand straight line, forehand center line, forehand diagonal line, backhand diagonal line, etc. If you hit the ball in the middle line, you can call it this: hitting the left side of the opponent's court is a left diagonal line, hitting the right side of the opponent's court is a right diagonal line, and hitting the middle is a middle ball. When addressing badminton routes, we should pay attention to the following problems: first, we should look at where the hitting point and landing point of the ball are close, the hitting point is close to the right line and the landing point is close to the center line, all of which are forehand balls. Secondly, according to the technical names used in hitting the ball, such as backhand rubbing, it can be divided into backhand rubbing straight line and backhand rubbing the ball.
In short, the basic route of badminton can be divided into five lines, namely: left straight line, middle straight line, right straight line, right diagonal line (right diagonal line) and left diagonal line (left diagonal line). According to the position of the batter's station (left, middle and right), each position can hit a straight line, a middle line and a diagonal line respectively, so nine lines can be deduced. Badminton's hitting lines are hard to describe, but there are only a few basic lines. As long as we master the rules, it will be of great benefit to our training and competition.
Verb (abbreviation for verb) racket angle and racket face direction
Racket angle refers to the angle between the racket face and the ground. The racket face direction refers to the position where the racket face faces.
There are seven kinds of racket angles: racket face down, racket face down, racket face up, racket face down, racket face up, racket face down, racket face down and racket face up.
The racket face direction can be divided into three types: racket face to the left, racket face to the right and racket face to the front.
The control of the racket angle and racket face direction has a great influence on the hitting quality, so we must carefully adjust the racket shape and racket face in each stroke in order to hit the ball that meets the quality requirements.
Sixth, the point of attack
The so-called hitting point is the space-time position of the racket touching the ball when the player hits the ball.
The hitting point includes three aspects: the first includes the height between the contact point between the racket and the ball and the ground; The second includes the front-back distance between the contact point and the body; The third includes the left and right distance from the body Choosing the right hitting point will determine the quality of hitting the ball, directly affect the strength, speed, arc and landing point of the player's hitting, and ultimately affect the player's hitting percentage, resulting in losing points or even failure. So it is very important to choose the right hitting point. Choosing the right hitting point should do the following two things: first, the judgment should be accurate, and second, the footwork should be in place (the footwork should be fast). As long as we do these two points, we can ensure that we can adjust to the most suitable position and ensure the hitting point.
Modern badminton originated in England. It is said that 1860, a banquet was held at Birmingham Manor in Glasgow, England. The guests had to stay indoors because of the rain. Several retired officers who came back from India introduced a game of playing shuttlecock back and forth with rackets across the net, which aroused great interest. Later, people named badminton as the second sport. The British Badminton Association was founded in 1893, and the first All England Badminton Championship was held in 1899. Since then, badminton has spread all over the world.
Badminton is a small ball game deeply loved by the masses. Because of its simple sports equipment, it is not limited by the venue. No matter where you go, whether there is a net or not, whether indoors or outdoors, as long as there is a small open space, you can carry out activities and exercise. The unique style of badminton, on the one hand, is a high-tech competitive event, on the other hand, it is a very popular activity for all ages. It can not only keep fit, but also be full of fun. Whether you are engaged in competitive sports or general mass fitness activities, you need to keep moving, jumping, turning around and hitting the ball on the court. Therefore, young men and women often play badminton, which can promote their growth and development, improve all aspects of their physical functions, cultivate their indomitable spirit of fighting for the game, and thus improve their physical fitness and physical and mental health.
[Edit this paragraph] Badminton knowledge
I always thought playing badminton rackets was the most expensive thing, but actually the ball was the most expensive thing. A YY Ti-5 racket is about 500 yuan. According to the calculation that playing badminton twice a week consumes three shuttlecocks, it takes about 12 strokes a year. Even if you play a mid-range ball for $40, it's almost $480 a year for Ti-5. As long as it is not particularly unlucky, a badminton racket can be used for at least 2-3 years, and it is generally no problem to use it for 5-6 years. Think about it. It's scary enough to knock out an advanced YONEX badminton racket in one year. No wonder I once read a news that an African badminton champion from Nigeria complained that the low level of badminton in Africa was because he couldn't afford enough badminton, because the training balls there cost 1 USD each, which was unbearable economically.
1. Definition of badminton in badminton competition rules of the International Badminton Federation;
1: The ball can be made of natural materials, artificial materials or their mixture. As long as the flying performance of the ball is similar to that of natural feathers wrapped in sheepskin and cork ball holders.
2. The ball should have 16 feathers fixed on the ball holder.
3. The feathers are 62-70 mm long, and the length of each ball's feathers from the ball support surface to the tip of the feather should be the same.
4. Feather tips are round, with a diameter of 58-68mm.
Feathers should be tied with thread or other suitable materials.
6: The bottom of the ball holder is spherical with a diameter of 25-28mm.
7: The ball weighs 4.74-5.50g..
8. Non-badminton:
8. 1: skirts made of synthetic materials or balls made of natural feathers.
8.2: The bearer is as stated in Rule 6.
8.3: The size and weight of the ball shall comply with the provisions of Rules 3, 4 and 7; However, due to the difference in specific gravity and performance between synthetic materials and natural feathers, the error cannot exceed 10%.
9: As long as the general style, speed and flight performance of the ball remain unchanged, with the approval of the relevant organizations, the standard ball may not be used in the following special circumstances.
9. 1: When the standard ball is not suitable due to the weather conditions at altitude;
9.2: Only when the change is beneficial to competition.
2. Classification of badminton hair:
High-quality badminton hair must use goose knife hair. If you use duck knife hair and other rough pieces, its quality is difficult to guarantee.
The classification of ball hair is very complicated. Because there is no unified national classification and numbering standard at present, the labels of badminton produced by various manufacturers are all customized. If different manufacturers have products with the same label, it doesn't mean that their quality is the same. Take Jinhe Factory as an example: all middle and high-grade badminton, that is, products with the word "A", are made of live plucked white goose feathers. First, it is divided into large, medium and small hairs according to the hair quality, then it is divided into one, two, three and four grades according to the hair quality, then it is divided into five standards according to the warping degree of the hair, and then similar hairs are classified according to the thickness of the hair stalk and the thickness of the hair. The 16 feathers used in the same badminton must be of the same category and as similar as possible. The more high-end products are used, the more consistent the 16 wig is, so as to ensure the flying quality of the products. Low-grade products, that is, ordinary leisure balls, are also made of white goose nest hair and camel hair, and the processing technology is the same as that of high-grade products, ensuring aesthetics and durability.
3. Classification of badminton ball heads:
According to the materials used, there are three common types: hard plastic, foamed plastic and cork. The first two kinds are mainly used for low-grade leisure badminton with low cost and poor performance. Middle and high-grade badminton all adopt natural cork ball heads, which can be roughly divided into three categories: integral cork ball heads, composite cork ball heads and recycled cork ball heads. Their structural diagrams are as follows:
It can be seen that the best ball head is of course natural cork, and the composite ball head has low cost and is not easy to break, but if the impact force is large, it is easy to break the lower part of recycled cork, thus affecting the impact performance. However, the cost of recycled cork ball head is lower, and the flying performance is better than that of non-cork ball head. Although its anti-strike ability is poor, it can meet the needs of specific users. For example, the 204A produced by Jinhe Factory is a low-priced medium-performance badminton suitable for beginners. Considering that beginners' hitting power is generally not too great, the main reason for badminton damage is that it is easy to hit the ball hair, so the regenerated cork ball head is not easy to crack, and its flying performance can fully meet the practice. Of course, the strength of cork ball heads recycled by different manufacturers sometimes varies greatly due to different production processes. In recent years, the ball head manufacturer has developed a ball head made of bionic plastic and natural cork, which is cheap and good, and the effect is ideal.
4. Identification of badminton Mao Mao quality;
High-quality badminton feathers must use high-quality goose feathers. The strength and toughness of goose feather are especially suitable for badminton, but its cost is high and the supply of raw materials is limited, so some badminton manufacturers with low requirements use duck feather. It is difficult to distinguish duck feathers from goose feathers only by appearance, and the well-made duck feather badminton has good flight performance. Because the hair stems of the two hair pieces are different, their hitting resistance is much worse than that of goose feather badminton, and normal hitting is easy to break because of the price of duck feather.
5. The difference between badminton glue:
The quality of glue directly affects the firmness and durability of badminton. Badminton glue can be divided into two categories: advanced resin glue and chemical glue. High-grade resin adhesive is superior to chemical adhesive in hardness and firmness, but its cost is relatively high, and it is generally used to make high-grade badminton. For example, 200A and 20 1A badminton made by Jinhe Factory are high-grade resin glue, while other kinds of badminton are high-strength chemical glue. In order to ensure the quality, the glue content of each badminton is higher than the requirements of national standards.
6. Quality inspection items of finished badminton:
Test items generally include: stability, impact resistance, weight, caliber, speed, adhesion fastness, hook fastness, etc. The manufacturers of these projects generally do not and do not need to test them item by item. When consumers buy badminton, they can test and compare their most concerned qualities according to the above items.
7. The difference between high-end products and low-end products:
Apart from the appearance, the main difference lies in the flying performance of the ball, that is, stability, speed, deformation when hitting and rotation when flying. High-grade badminton requires a lot of wigs, and the appearance and quality of wigs on a ball 16 are similar, so as to ensure the high standard requirements of badminton, which leads to its higher price.
8. The relationship between speed, weight and caliber of badminton;
In the same area, the flying speed of badminton mainly depends on its overall weight, caliber, hair type, the difference between the left and right hairs, and the weight ratio of the ball head to the ball body. Generally speaking, the caliber of badminton manufactured by the same factory is fixed. For example, the caliber standard of Golden Carved Badminton is 66.5mm±0.5mm, that is, 66-67 mm. At this time, the main factors that determine the ball speed are the overall weight of the ball and the weight ratio of the ball head to the ball body. So according to the overall weight of the ball, we can know its approximate flying speed and where it is suitable.
9. What kind of badminton should I choose in different altitude climate areas?
The most basic requirement of badminton is that the speed or weight of the ball used must be appropriate, otherwise many techniques will be difficult to play. Badminton with the same weight will fly at different speeds in different areas, because the weight of the ball is closely related to altitude and climate. The high air density at high altitude will reduce the air resistance when badminton flies, so the weight of badminton used at high altitude will be reduced. At low altitude, the air density is high, and the air resistance of badminton in flight is great, so the weight of badminton used at low altitude is heavier. Take the golden eagle products as an example: Shanghai: 5.2g, Guangzhou: 5. 1g, Kunming: 4.7g, Chengdu: 4.9g. In addition, the air humidity and temperature also have certain influence on the speed of badminton, but the altitude has the most obvious influence.
10. What are the disadvantages of using heavy badminton or light badminton to the racket and human body?
The overall weight of badminton is too heavy or the ball head is too heavy, which will cause great vibration when hitting the ball, which will have a great impact on the badminton racket and badminton line and reduce the service life of the badminton racket and badminton line. The most obvious thing is that the service life of badminton line will be greatly shortened. On the other hand, long-term vibration will be transmitted to the batter's arm, which will also have some bad effects on the arm. If the weight of badminton is too light, because the ball is not in place, the batter will send out more strength to achieve the goal of hitting the ball in place, which will easily cause fatigue and injury to the arm. So choosing the right weight badminton can not only make you enjoy badminton better, but also reduce your risk of injury.
1 1. What's the manufacturing process of badminton?
The production technology of badminton is divided into three parts: wool making, head making and combination.
Wool making process: wool washing, drying, wool selection, wool washing, classification, warping and wool mixing.
Head making process: grinding, repairing, wrapping, baking, peeling, drilling and weighing.
Combined technology: hair planting, glue injection and drying, thread hooking, adjustment, glue brushing and drying, head wiping, edge winding, weighing, applique, finishing, stability testing, weighing, packaging and warehousing.
